Objectives: Patients with Diabetic Kidney Disease (DKD) and foot ulcer have poor prognosis. However, no study have found association of diabetic foot ulcer (DFU) with diabetic kidney dysfunction and their co-existing risk factors. Materials and Methods: This cross sectional study collected the data for 10,680 patients for 15 years. All variables were analyzed biochemically and statistically by standardized methodology. Results: Levels of HbA1c, creatinine, systolic and diastolic blood pressures, microalbuminuria, spot urine protein, and spot urine protein to creatinine ratio were higher among the groups with foot ulcers (p-value < 0.0001 for all). Average ABI was observed to be lower among the groups demonstrating nephropathy and DKD (p=0.025 and 0.022 respectively. DFU was significantly associated with HTN (odds ratio 2.2; 95% CI 1.66 to 2.9; p < 0.0001), nephropathy (odds ratio 4.77; 95% CI 3.53 to 6.5; p < 0.0001) and DKD (odds ratio 4.77 and 6.83; 95% CI 4.6 to 10.2; p < 0.0001). HbA1c of 7.8% was 60% sensitive and 52% specific for the development of DFU. Creatinine of 1.2 mg/dl was 75% sensitive and 48% specific for DFU. Spot urine protein excretion from nephrons of 35 mg/dl was 88% sensitive and 90% specific for the development of DFU. Conclusion: Nephropathy/DKD are risk factors for the development of DFU. With optimal diabetes control, regular and routine assessment of the feet and early screening of diabetic patients for neuropathy, nephropathy, hypertension, dyslipidaemia and other diabetic complications are essential. Doi: 10.28991/SciMedJ-2021-0304-6 Full Text: PDF

ABSTRACTIt has been cited in the research that patients with diabetic kidney disease (DKD) and foot ulcer have poor prognosis; and foot ulceration is associated with kidney dysfunction. However, no study have found association of diabetic foot ulcer (DFU) with diabetic kidney dysfunction and their co-existing risk factors including blood pressure, serum creatinine, microalbumin, spot urine protein, HbA1c and associations of nephropathy and DKD with low ankle brachial index (ABI). We monitored, collected and analyzed the data for 10,680 patients for a duration of more than 13 years. 12% of patients demonstrated DFU. Nephropathy was observed in 39% of patients; 43% was hypertensive while 15% demonstrated DKD or CKD. Levels of HbA1c, creatinine,, systolic and diastolic blood pressures, microalbuminuria, spot urine protein, and spot urine protein to creatinine ratio were higher among the groups with foot ulcers (p-value < 0.0001 for all). Average ABI was observed to be lower among the groups demonstrating nephropathy and DKD with significant p-values (p=0.025 and 0.022 respectively). Pearson’s χ2 and logistic regression with odds ratio were also analyzed for DFU with HTN, nephropathy and DKD. DFU was significantly associated with HTN (odds ratio 2.2 ; 95% CI 1.66 to 2.9; p < 0.0001), nephropathy (odds ratio 4.77 ;95% CI 3.53 to 6.5; p < 0.0001) and DKD (odds ratio 4.77 and 6.83; 95% CI 4.6 to 10.2; p < 0.0001). ROC was used to find out cutoff values, sensitivity and specificity. HbA1c of 7.8% was 60% sensitive and 52% specific for the development of DFU (AUC = 0.58; 95% CI 0.521 to 0.624; p < 0.0006). Creatinine of 1.2 mg/dl was 75% sensitive and 48% specific for DFU (AUC = 0.58; 95% CI 0.640 to 0.715; p < 0.0001). Spot urine protein excretion from nephrons of 35 mg/dl was 88% sensitive and 90% specific for the development of DFU (AUC = 0.585; 95% CI 0.555 to 0.616; p < 0.0001). Our data has demonstrated the first time such associations and confirmed that nephropathy or renal failure are risk factors for the development of DFU. HbA1c should be optimal and near to the targets to improve wound healing. Our study has prompted diabetologists for regular and routine assessment of the feet and early screening of diabetic patients for neuropathy, nephropathy, hypertension, dyslipidemia and other diabetic complications as well.

In the present study, a total of 428 South Indian subjects were divided into four different groups, consisting of individuals with type 2 diabetes without any other complications (T2DM), T2DM subjects with stage 2 and 3 diabetic kidney disease (CKD), T2DM subjects with grade 2 or 3 diabetic foot ulcer (DFU) and T2DM subjects having both diabetic kidney disease and diabetic foot ulcer (CKDDFU). The study was conducted ambispectively by comparing the changes in renal function among two consecutive periods, i.e., the period prior to the development of grade 2 and 3 diabetic foot ulcer (retrospectively) and after the development of DFU (prospectively). A gradual and uniform reduction of eGFR was observed throughout the study period in the subjects affected with either CKD or DFU alone. Whereas in subjects with both CKD and DFU, there was a sharp decline in the eGFR during the six months prior to the baseline, i.e., the period in which the development of ulcer and its progression to grade 2 or 3 happened. Remarkable elevations in the levels of TGF-β1 and CCN2 (CTGF), as well as a significant reduction in the level of CCN3 (NOV), were observed in the serum of CKDDFU group subjects, compared to the other groups. Increased production of TGF-β1 in response to the inflammatory stimulus from multiple sites in CKDDFU subjects caused a subsequent down-regulation of CCN3, followed by the activation of a large quantity of CCN2.

Aim: Atherosclerosis involves vascular endothelial damage and lipid metabolism disorder, which is closely related to the occurrence and development of diabetic kidney disease (DKD). However, studies on non-high albuminuria DKD (NHADKD) with an albumin to creatinine ratio (ACR) <30 mg/g are rare. This study is to investigate the relationship between atherogenic factors and the occurrence of NHADKD. Methods: Serum lipid indicators, lipoprotein-associated phospholipase A2 (Lip-PLA2) and homocysteine levels were measured in 1116 subjects to analyze their relationship with NHADKD. Results: Among all subjects, Lip-PLA2 had the closest but relatively weak correlation with ACR ( r = 0.297, p < 0.001) and only homocysteine was moderately correlated with eGFR ( r = −0.465, p < 0.001). However, in patients with NHADKD, these atherosclerotic factors were weakly correlated or uncorrelated with eGFR (max. | r| = 0.247). Stratified risk analysis showed that when ACR was <10 mg/g, homocysteine [OR = 6.97(4.07–11.95)], total cholesterol (total-Chol) [OR = 6.04(3.03–12.04)], and high-density lipoprotein cholesterol (HDL-Chol) [OR = 5.09(2.99–8.64)] were risk factors for NHADKD. There was no significant difference of OR between these three factors ( Z = 0.430–1.044, all p > 0.05). When ACR was ⩾10mg/g, homocysteine [OR = 17.26(9.67–30.82)] and total-Chol [OR = 5.63(2.95–10.76)] were risk factors for NHADKD, and ORhomocysteine was significantly higher than ORtotal-Chol ( Z = 3.023, p < 0.05). Conclusions: The occurrence of NHADKD may be related to the levels of homocysteine, total-Chol, HDL-Chol, and Lip-PLA2 in blood. Among them, homocysteine may be most closely related to NHADKD.

Roger Pecoraro made important contribution to diabetic foot research and is primarily responsible for instilling in me an interest in these complications. Our collaboration in the final years of his life led to the development of the Seattle Diabetic Foot Study. At the time it began, the Seattle Diabetic Foot Study was perhaps unique in being a prospective study of diabetic foot ulcer conducted in a non-specialty primary care population of patients with diabetes and without foot ulcer. Important findings from this research include the demonstration that neurovascular measurements, diabetes characteristics, past history of ulcer or amputation, body weight, and poor vision all significantly and independently predict foot ulcer risk. A prediction model from this research that included only readily available clinical information showed excellent ability to discriminate between patients who did and did not develop ulcer during follow-up (area under ROC curve=0.81 at one year). Identification of limb-specific amputation risk factors showed considerable overlap with those risk factors identified for foot ulcer, but suggested arterial perfusion as playing a more important role. Risk of foot ulcer in relation to peak plantar pressure estimated at the site of the pressure measurement showed a significant association over the metatarsal heads, but not other foot locations, suggesting that the association between pressure and this outcome may differ by foot location. The Seattle Diabetic Foot Study has helped to expand our knowledge base on risk factors and potential causes of foot complications. Translating this information into preventive interventions remains a continuing challenge.

Abstract The presence of albuminuria in patients with type 2 diabetes mellitus is a marker of endothelial dysfunction and also one of the criteria for diagnosing diabetic kidney disease. The present study aimed to identify associations between cardiovascular risk factors and renal albumin excretion in a group of 218 patients with type 2 diabetes mellitus. HbA1c values, systolic blood pressure, diastolic blood pressure were statistically significantly higher in patients with microalbuinuria or macroalbuminuria compared to patients with normoalbuminuria (p <0.01). We identified a statistically significant positive association between uric acid values and albuminuria, respectively 25- (OH)2 vitamin D3 deficiency and microalbuminuria (p <0.01).
